Question

What is the domain of this function?

O x>0
O {xlx<8}
O {x|0 < x <8)
O {xlx<0x 8)

Answer 1

Given:

Consider the below figure attached with this question.

To find:

The domain of the graphed function.

Solution:

Domain is the set of input values or x-values.

From the given graph it is clear that the function has one end point at (0,9) and an arrow at (8,1). It means it is not a line because it is a ray that moves further from point (8,1) in the downward direction.

The minimum value of x is 0 and their is no maximum value of x because graph of the function is a ray. So, the domain of the given function is:

`\text{Domain}=\x\geq 0\`

Therefore, the correct option is A.
